FH33-6S-0.5SH FFC/FPC Connector Equivalent & Substitute Parts

Part Overview

The FH33-6S-0.5SH is a 6-position FFC/FPC connector manufactured by Hirose Electric Co Ltd, designed for surface mount, right-angle applications with 0.5mm pitch contacts. This connector features a flip lock mechanism and zero insertion force (ZIF) design, making it suitable for flat flexible cable termination in compact electronic assemblies. The part is currently active in production with full RoHS compliance and UL94 V-0 flammability rating. Substitute parts are identified when inventory constraints or supply chain requirements necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for FFC/FPC connectors is determined by strict equivalence across the following critical parameters:

Position count, pitch spacing, mounting orientation, contact configuration, and termination method establish the primary substitution criteria. The FH33-6S-0.5SH substitute FH33-6S-0.5SH(10) maintains identical specifications across all these parameters: 6 positions, 0.5mm pitch, surface mount right-angle orientation, bottom contacts, and solder termination.

Electrical ratings including voltage (50V) and current capacity (0.5A) must match exactly. Mechanical compatibility requires identical FFC/FPC thickness (0.30mm), height above board (1.20mm), and locking mechanism (flip lock). Material composition, contact finish, and housing material remain constant across the substitute relationship.

Compliance certifications including RoHS compliance and UL94 V-0 flammability rating are maintained. Moisture sensitivity level (MSL 1) ensures equivalent handling and storage requirements.

Engineering Selection Recommendations

Both FH33-6S-0.5SH and FH33-6S-0.5SH(10) are active production parts from Hirose Electric Co Ltd with identical electrical and mechanical specifications. Selection between these parts is based on inventory availability and supply chain requirements rather than technical differentiation.

FH33-6S-0.5SH(10) offers higher inventory availability (2060 units) compared to FH33-6S-0.5SH (612 units), making it suitable for high-volume production runs or extended lead time mitigation. Both parts maintain full RoHS compliance and UL94 V-0 flammability certification, ensuring regulatory compliance across all applications.

The identical parameter set across voltage rating, current capacity, operating temperature range, and mechanical dimensions confirms direct interchangeability in PCB assembly and flat flexible cable termination applications.

Frequently Asked Questions (FAQ)

Q: Are FH33-6S-0.5SH and FH33-6S-0.5SH(10) electrically interchangeable?

A: Yes. Both parts maintain identical voltage rating (50V), current rating (0.5A), and operating temperature range (-55°C ~ 85°C). Electrical performance is equivalent.

Q: What determines compatibility between these FFC/FPC connectors?

A: Compatibility is established through matching position count (6), pitch spacing (0.5mm), mounting orientation (surface mount right-angle), contact configuration (bottom contacts), and termination method (solder). All these parameters are identical between the main part and substitute.

Q: Can these connectors accommodate different FFC/FPC cable thicknesses?

A: No. Both connectors are specified for 0.30mm FFC/FPC thickness. Cable thickness outside this specification will not mate properly with the flip lock mechanism.

Q: What is the significance of the MSL 1 rating?

A: MSL 1 (Unlimited) indicates these connectors have unlimited shelf life under standard storage conditions. No special moisture control or baking procedures are required prior to assembly.

Q: Are there packaging differences between FH33-6S-0.5SH and FH33-6S-0.5SH(10)?

A: Both parts are supplied in Tape & Reel (TR) packaging. The designation difference reflects internal Hirose product line management and does not affect form, fit, or function.

Q: What is the height constraint for these connectors in compact assemblies?

A: The height above board is 0.047" (1.20mm). This dimension must be verified against PCB layout and enclosure clearance requirements for right-angle surface mount applications.
